It will be realized that whereas I havedescribed and shown a practical and operative device, and several variations thereof, nev- 'ertheless I do not wish to be limited spes cificall as any particular form or application my device. I therefore wish my descgiptiop and drawings to be taken as in a rather than as limiting me to my specific showing. a

The use and operation of my invention are as follows: I i the emplo ment of wire mesh baking pans, for examp e'for biscuits, it is extremely ufi bt't-ant that the entire area of the pan be ut ited. If, in a pan of this type, the edge MP0 the" mesh is clamped down y a frame member or' a clamping element which projects inwardly from the edge of the pan, the space occupied by such member or element is lost. Furthermore, in the use of such pans .for example in the baking and handling 0 the batter is deposited at a number of points, .some'of the batter is likely to be deposited omthe securing means or clamping edge of the frame. Such batter, if deposited on the frame or edge, must be scraped off by the mad at the machine, or else will result in the baking of unsalable material. The result is 40. ,an extra expense of labor, or a loss in waste, 'or a 10$ in time or in labor cost, and a reduction in output. I obtain a maximum output at minimum expense and with minium wastage by providing a wire mesh pan in which the mesh isavailable from ed e to exfi tendlng throughout'the entire effective width the free surface ofthe wire mes of the pan, except for the ver slight neces- Wrojection of the guard ange.

110 the employment of a free and unrestricted'batter receiving surface of maxinttlmarea isimportant, it is also important thatfthe edge of the mesh be protected. This is particularly the case because trays of this [3 ty passthrough conveying machinery and bafing machinery; Also they are subject to rough usage and heavy handling.v The employees pitch them about, in practice, with a carelessness which is likely to be destruc- .tive'ofany but well built pans. The proedge or flange B or the outward pro- {ection of the member C or D serve to provide ateral protection and to prevent the batter-f .or wear of the mesh against the sides of flfi cqnveyingr machinery or ovens. This is broad sense illustrative. and diagrammatic.

I surface, a frameelement about the edge of blSCllltS,'if the pan is conveyed beneath a mechanism for depositing batter in which ing pan which includes acircumferential vitally important because the bent ed e of the mesh is particularly vulnerable an subject to wear. The individual wires, if battered, becomebent or broken and the panes a whole becomes shortly unusable.

With my pan I provide a baking surface or batter supporting surface which is one hundred per cent usable. The wire meshfedge extends practically to the very edge 0 pan. When the pans go through batter depositing machines the dies which are used to deposit batter can deliver batter only to the level supporting surface adapted to receive it. There is an elimination of loss in waste and time. The edge ofthe meshis retested, and the life of the pan is lengthe I claim:

1; As a new article, of manufacture, a baking pan which includes a wire mesh baking said mesh, the, wire mesh baking surface extending over said frame to the effective edge of thepan, the u per surface of said wire mesh bakin mem 'er being free throughout the area of t e pan, and a laterally extending guard for theedge of said wire mesh baking surface member. s y r 2. As a new article of manufacture, a baking. pan which includes a wire mesh baking surface, a frame element about the edge of said mesh, the wire mesh baking surface ex- M tending over said frame to the eflectiveedge of the pan, the u per surface of said wire mesh baking member being free throughout the area of the pan, and a laterally extend in guard for the edge of said wire mesh ba ing surface member, said guard member forming part of the said frame element.

, 3. As a new article of manufacture, a baking pan which includes a circumferential frame member having an upper flange and a lower flange, the lower flange extendingoutwardly beyond the edge of the upper, and a wire mesh baking surface member the edge of which penetrates between thetwo flanges, the body of which rests upon the upper flan e ge of tie and is bent downwardly about the e upper flange. K V a V r 4. As a new article of manufacture, a bakframe member having an upper element and Q a lower element, the lower element extendi outwardly beyond the edge, of the upper, an

a wire mesh baking surface member, theedge of which penetrates between the two elements but is contained within the periphery of the lower element, theruppr surface of said wire mesh baking member beim free throughout the effective upper area of the mesh.

5. As a new article of manufacture, abaking pan whichincludes a wire meshbaking y surface member, the outer edgeof said wire mesh bakingsurface member being inwardly recur-ved, a clrcumferential framemember in operative contact. with;said inwardly re-"lso curved portion and a laterally extending guard for the edge ofsaidwire mesh baking Q surface member, the upper surface of the wire mesh member being free throughout the effective upper area.

6. As a new article of manufacture, a bakingpan which includes a wire mesh baking surface, a frame element about the edge of said mesh, the wire mesh baking surfaceex- 1D tending over said frame to the effective edge of the pan, the 11 per surface of said wire mesh baking mem er being free throughout the area of the pan.
